This day marks the time when Prince Siddhartha Gautama, a spiritual teacher and founder of Buddhism, positioned himself under the Pipul tree and vowed to remain there until he attained supreme enlightenment. Buddhist traditions vary as to what Siddhartha's experience was while meditating under the tree, but all agree that upon the rising of the morning star, he had experienced enlightenment and attained Nirvana: a state of being free from suffering and broken from the cycle of rebirth.
